# ET-INV-001: Modelo de Datos Investment

**Epic:** OQI-004 Cuentas de Inversión
**Versión:** 1.0
**Fecha:** 2025-12-05
**Responsable:** Requirements-Analyst

## 1. Descripción

Define el modelo de datos completo para el schema `investment` en PostgreSQL 15+, incluyendo:
- Productos de inversión (agentes ML)
- Cuentas de inversión de usuarios
- Transacciones (depósitos, retiros, distribuciones)
- Solicitudes de retiro
- Performance diaria de cuentas
- Distribuciones mensuales de utilidades

```sql
-- Seed data para testing
INSERT INTO investment.products (
    name, description, agent_type, min_investment,
    performance_fee_percentage, risk_level, ml_agent_id
) VALUES
(
    'Swing Trader Pro',

```

### 9.2 Tests de Integridad

```sql
-- Verificar constraints
DO $$
BEGIN
    -- Test: min_investment positivo
    BEGIN
        INSERT INTO investment.products (name, agent_type, min_investment, risk_level, ml_agent_id)
        VALUES ('Test', 'swing', -100, 'low', 'test-agent');
        RAISE EXCEPTION 'Should not allow negative min_investment';
    EXCEPTION WHEN check_violation THEN
        -- Expected
    END;

    -- Test: unique user_product
    BEGIN
        INSERT INTO investment.accounts (user_id, product_id)
        VALUES ('user-1', 'product-1');
        INSERT INTO investment.accounts (user_id, product_id)
        VALUES ('user-1', 'product-1');
